This synthesis will be of interest to state Department of Transportation (DOT) geotechnical, bridge, and pavement engineers, engineering geologists, consultants involved with ground penetrating radar (GPR) investigations for state DOTs, and researchers. It describes the current state of the practice of using GPR for evaluating subsurface conditions for transportation facilities. This was accomplished by conducting a literature search and review and an extensive survey of U.S. and Canadian transportation agencies and practitioners, as well as limited international information collection. GPR is a noninvasive nondestructive tool used in transportation applications such as evaluation and characterization of pavement systems, soils, and environmental problems. This report of the Transportation Research Board presents information on the principles, equipment, logistics, applications, and limitations of GPR pertaining to transportation applications. Selected case studies for which ground truth information is available are presented. In addition, an extensive bibliography and glossary are provided as well as appending information about GPR manufacturers from their literature.

An objective view of the relative advantages and limitations of the nondestructive testing and evaluation methods that are currently used in the inspection of bridge decks is presented and discussed. The three main nondestructive testing technologies that were evaluated are impact-echo, ground penetrating radar, and infrared thermography. Nondestructive testing and evaluation procedures, including methodology and equipment to evaluate concrete bridge decks with asphalt overlays, are also presented and discussed. Current results indicate that a combination of ground penetrating radar and infrared thermography would provide the best methodology for evaluating the structural integrity, e.g., delaminations, of concrete bridge decks with overlays. Furthermore, current results also indicate that the impact-echo method shows promising future development towards the nondestructive evaluation of bridge superstructures.

This book gives information on non destructive techniques for assessment of concrete structures. It synthesizes the best of international knowledge about what techniques can be used for assessing material properties (strength) and structural properties (geometry, defects...). It describes how the techniques can be used so as to answer a series of usual questions, highlighting their capabilities and limits, and providing advices for a better use of techniques. It also focuses on possible combinations of techniques so as to improve the assessment. It is based on many illustrative examples and give in each case references to standards and guidelines.

Effective maintenance of bridge structures comprises a broad spectrum of plans for repairs and services implemented to enable bridges to perform their intended function. These include in-depth inspection, fatigue analysis, design of mitigation measures and construction to avert component deterioration. Several incidents of in-service and under construction bridge failures have recently taken place. These dramatic failures emphasize the importance of risk-based inspections and analysis of real-life data to evaluate reliability of bridges. To effectuate benefits of reliability analysis in bridge maintenance, work on theoretical reliability must be equipped with practical analytical tools. Such an approach must underscore risk elements and identify processes to manage risk and avoid unexpected outcomes of failures and service disruption of bridges. The devastating earthquakes of February 6, 2023, in the southern region of Turkey near the northern border of Syria, which claimed tens of thousands of lives, caused enormous structural damage and staggering economic losses. These seismic events brought to focus on the vitality of instilling infrastructure routes that must accommodate emergency management plans to integrate the influx of medical and rescue response teams. The safe operation of bridges along these routes is indispensable for mobilization and deployment of rescue teams, medical personnel, humanitarian assistance, and the supply of food and water. The reliability of access routes and bridges is defined by their ability to adequately function as planned to effectuate emergency management plans, in the event of a similar seismic event, anywhere in the world. Risk-Based Strategies for Bridge Maintenance contains selected papers presented at the 11th New York City Bridge Conference (New York City, USA, 21-22 August 2023), and discusses issues of reliability, risk assessment, management, maintenance, inspection, monitoring, design, preservation, and rehabilitation of bridges. The book is aimed at bridge engineers.

The fourth Structural Materials Technology NDT Conference was held in Atlantic City, New Jersey, with over sixty speakers presenting on a wide variety of topics. The goal of this conference was to inform engineers and researchers of the new nondestructive testing/nondestructive evaluation (NDT/NDE) technologies and techniques available for use in transportation construction. The use of alternative materials is challenging NDT/NDE professionals to develop new methods or modify existing techniques to address quality control, quality assurance, and long-term monitoring of structures built or strengthened with these materials. One such alternative is fiber-reinforced polymer (FRP) products. This conference included papers on this topic and a panel discussion that focused on the future of NDT/NDE technologies for structures built or rehabilitated with FRP composites. These proceedings contain the 62 papers that were presented at the conference, arranged according to session number. An author index is included.
